Least common multiple calculator

A least common multiple calculator that will find for you the smallest multiple two numbers have in common.

Enter your first number into the box on top.

Enter your second number into the box in the middle.

Hit calculate et voilà! Recall that the multiple of a number is any number that divides the number evenly.

For example multiples of 2 are 0, 2, 4, 6, 8, 10, 12, 14, ....

multiples of 3 are 0, 3, 6, 9, 12, 15, .....

As you can see common multiple for 2 and 3 so far are 6 and 12. However, the smallest one is 6 so 6 is the least common multiple

Notice that the least common multiple of 0 and any number is 0

For example, least common multiple of 0 and 4 is 0

Having said that, the calculator will not compute least common multiple if you enter 0 as a number.

Please enter the first number:
